This blog is about the Linux Command Line Interface (CLI), with an occasional foray into GUI territory.
Instead of just giving you information like some man page, I hope to illustrate each command in real-life scenarios.

If you pipe the output of grep to grep, he escape characters will mess up the second grep. In most cases, such piping shouldn't matter. However, if you do a 'for' loop to extract s.t. (variable names, for instance) from one file, and then grep the results in other files, you'd need to use --color=NEVER or --color=AUTO on the first instance.
